Transparent, translucent and opaque materials

Transparent

Transparent materials let light pass through them in straight lines, so that you can see clearly through them. Glass is an example of a transparent material. Illustration of light entering a window

Translucent

Translucent materials let some light through, but they scatter the light in all directions, so that you cannot see clearly through them. Tissue paper is an example of a translucent material. Illustration of a torch shining onto tissue paper

Opaque

Opaque materials do not let any light pass through them. They block the light. Wood is an example of an opaque material. Illustration of the sun casting a shadow of a tree
